PLOW.

SPECIFICATIO forming part of Letters Patent No. 326,591, dated September 22, 1885.

Application fi) ed March 6, 1885. (No model.)

To all whom t may concern,.-

Be it known that I, JAMEs D. RoBERsoN, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Mis- 5 souri, have invented a new and useful Improvement in Plows, of which the following is a specification.

My invention consists, iirst, in the combination f a hinged plow-beam, a rear hinged landside-bar vhaving a screw-standard and adjusting-nuts, and another screw-standard provided With adj usting-nuts and having abracket or arm which connects with the standard of the rear hinged landside, said screw-standard being supported upon the inner landside-bar of the plow and supporting the rearend of the beam second, in acombinat-ion of a hinged beam, a screw-standard, an inner landsidec bar, and a hinged landside having adjusting 2O devices.

The aforesaid improvements serve for effectually sustaining the parts of the plow, while the depth of the point of the. plow, the position of the rear landside, and the beam can be adjusted as circumstances require.

In the accompanying drawings, Figure l is a land-side elevation of my improved plow, portions being broken away and sectioned in order to illustrate more plainly the construction. In this View the rear landside is shown on a horizontal plane with the beam and sole of the plow. Fig. 2 is also a land-side elevation, the beam and sole of the plow being shown on an incline plane and the rear landside-bar on a horizontal plane in full black lines and by dotted lines on the same and different incline planes with the beam and sole of the plow. Fig. 3 is a broken horizontal section of the plow, the beam and adjusting-nuts being removed. Fig. 4 is a broken detail view of the beam and its standard-supporting plate, and Fig. 5 is a detail View of the supportingplate ot' the beam and a portion of the standard.

The construction of my plow is as follows: The mold-board A, share B, and standard C, and front landside-bar, D, are of suitable form and united upon an inner landside-bar, E, by bolts or screws and a bent Vbrace. (Not 50 shown.) The landside facing of the standard Q adjoins the front landside by an angular joint, a, and forms a support for the upper portion of the landside edge of the moldboard. In rear of the standard theinner landside-bar, E, extends a considerable distance and forms a support for the landside-handle L, as well as a curved'screw-threaded standard, G,'which has a slotted bracket, G, eX- tending back horizontally, and is rmly bolted to the inner side of the bar E, being bent inward from the landside at its lower end, so as to have its upper portion come in line with the standard (l.

To the inner landside-bar a rear outer landside-bar, H, is connected by a hinge pivot or bolt, b, said bolt being passed through the lower end of the landside-handle L, and thus `serving for securing it, as well as the handle H, in position. The front 'end of the bar H is curved and ts a correspondingly-curved socket, c, formed in the heel of the standard,

as shown.

Near the rear end of the bar H an upright screw-standard, l, is firmly applied, and this standard passes through an oblong slot, d, 7 5. formed in the bracket G of the screw-standard G, and allowing the standard freedom while being screwed up or down. On the under and upper sides of the bracket G', adjusting and confining nuts e e are applied on the 8o screw-threaded portion e2 of the screw-standard I.

The plow-bearnJ is connected to the standard C by means of a broad-surfaced plate, K, which is connected byahorizontal pivot-bolt, f, to the standard, and a vertical pivot-pin, f5', and an adjusting and conning bolt, f2. The bolt f2 passes up through a transverse oblong slot, f7., in the plate K, and through the beam, receiving a nut, f3, on its upper end. The 9o bolt]2 can be moved laterally in slot f7 when desirable. The extreme rear end of the beam is formed with a transverse oblong slot, fi, so as to permit of lateral adjustment of the beam, and through this slot the upper end of the screw-standard G is passed, and below and above the standard screw-nuts f5 f6 are applied upon the screw-threaded portion f8 of the standard, as shown.

The mold-board handle L is fastened to the roo rear under side of thc mold-board, and to the fastening-bolt at the lower end of this handle,

as Well as to the screw-standard G and inner landside-bar, a brace, M, is applied, as shown, or in any other suitable manner.

The clevis J of the plow is bolted centrally' on thefront end of the beam, and the draft is therefore always central.

From the foregoing description, in connection with the drawings, it will be seen that when it is desired to cant the beam on the pivot-pin f, so as to adapt the plow for heavy or light draft, it can be done by turning the upper nut, f5, of standard G backward and the lower nut, f6, forward; or, if it is desired to have the front end of the beam stand higher, this can be accomplished by turning the nut f backward and the nut f5 forward, and by loosening the nut f3 of the bolt fl and the nuts f f6 of the standard the beam can be swung around horizontally either toward or from the land, so as to have the point and landside of the plow stand more or less out of line with the beam, accordingly as may be desired; and to insure the point of the plow entering deeper into the soil, and thus plow a deeper furrow, the lower nut, e, of the standard I is turned backward and the upper nut, e, forwaidwhich operation moves the rear landside-bar, H, from the position illustrated by dotted lines to the position shown in full black lines in Fig. 2 with respect to the inclined portion of the beam and frontlandside, D, and the plow will be caused to enter the soil to a greater or the desired depth. By raising the rear end of the rear laiidside-bar, H. the depth of plowing can be decreased. and this can be accomplished by turning the lower nut, e', backward and the upper nut, e, forward.

In making the adjustments of the rear landside it will be understood that the heel of the landside-bar may be lowered from the point x to the position indicated by in Fig. 2, and it will also be understood that the adjustment can be made to any extent desired.

In constructing the standard G its lower portion is set back on the inner side of the inner landside-bar, so as not to interfere with the operation of plowing, and the standard I and the bracket G' are placed inside the rear landside-bar for the same purpose; and it is in tended to have the slots in the rear end of the beam and in the front end of the plate K of such length as to permit the front end of the beam to be moved laterally to any extent required.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The hinged rear laudside-bar, H. provided with an adjusting screw-standard and nuts, and the inner landside-bar, E, provided with the adj Listing-standard G, bracket G', and nuts, with the plow-beam J and standard C, hinged together at f, substantially as and for the purpose described.

2. The combination of the standard C, beam J, hinged to said standard, the adjustingstandard G, inner landside-bar, E, and the rear landside-bar, H, provided with suitable adjusting devices, substantially as described.
